Some Himalayan glaciers have actually grown during the past decades, according to a report in the journal Nature Geoscience. We took along a BBC-quality recorder with us on our 2012 Nepal expedition, and spoke to some of the scientists trying to get better data from the mountains.

During our recent Uganda & Congo expedition we re-discovered glaciers on the Congo side of the Rwenzori Mountains. The area had not been explored for decades. Wired writer Ian Daly travelled with us and wrote this in-depth feature about the expedition.
